LS320 Owner's Manual

Introduction

The McIntosh LS320 Loudspeaker System is designed for
Home Theater and Music Reproduction. It is a two-way
system with one 8 inch LD/HP
dome tweeter. The LS320 is designed to work as a Left or
Right (Main) Loudspeaker in a Music System or as a Main
or Surround Loudspeaker, in a Home Theater System.
The LS320 Loudspeaker performance is equivalent to
the quality of McIntosh’s legendary line of Amplifiers,
Preamplifiers, Signal Processors and Signal Sources, with-
out imparting distortion or coloration of its own. It also
complements the capabilities and the remarkably low dis-
tortion of McIntosh Power Amplifiers.
Many of today’s loudspeakers are designed only for
Home Theater applications. Not so with the LS320. It is
also designed for the accurate reproduction of music. Mo-
tion picture sound effects, explosions, screams, and vehicle
crashes require a wide dynamic range and high sound lev-
els. These sounds are such that a speaker system having
moderate distortion would reproduce them with little au-
dible difference. This is not true with the reproduction of
music. Music is by nature and definition harmonious. To
reproduce it accurately, all forms of distortion, both har-
monic and intermodulation, must be kept to a minimum.
This has been the result of the design of the new McIntosh
LS320 Loudspeaker System. Each loudspeaker element
and crossover component has been carefully designed for
durability, efficiency, and above all, low distortion. The
McIntosh LS320 Loudspeaker System will reproduce mu-
sic accurately and function as an excellent Home Theater
Loudspeaker.

Performance Features

•
Gold Plated Input Connectors
The LS320 input connectors are gold plated for superior
corrosion resistance and high electrical conductivity.
•
Acoustic Edge-Hole Elimination
An “edge-hole” is a severe dip in the high frequency
response of a speaker system, caused by the relative
distance of the dome tweeter to the edge of the speaker
cabinet. If the distance to the edge of the cabinet is the
same on both sides of the dome tweeter, cancellation of the
sound occurs at a specific frequency. McIntosh guards
against this phenomenon with a special tweeter mounting
that eliminates the “edge-hole” effect. A specially designed
tweeter bezel and perforated grill mask the tweeter
mounting to maintain a symmetrical appearance.

Introduction and Performance Features
•
Patented LD/HP Technology
The McIntosh Low Frequency Loudspeaker Element
features the patented LD/HP motor structure. This design,
when compared to conventional Loudspeaker Elements,
reduces distortion significantly. It also increases power
handling and efficiency.
•
Shielded Magnetic Field
The LS320 may be used in Home Theater Installations
near a television receiver or monitor without causing the
television image to degrade. McIntosh has designed special
shielding around the magnetic structure of the LS320
Loudspeaker Elements to prevent interference.
•
High Power Handling
The Loudspeaker Elements and crossover components of
the LS320 are all chosen for use with powerful amplifiers
up to 200 watts.
•
High Efficiency
The Loudspeaker Elements used in the LS320 Loudspeaker
System have also been designed for high efficiency. As a
result any McIntosh Power Amplifier, even our smallest,
will provide satisfying room filling sound.
•
Automatic Overload Protection
The LS320 has built-in Loudspeaker Element Protection in
the form of two automatic resetting solid-state devices as a
part of the crossover network.
